And having an High Priest over the house of God - Over the spiritual house of God; that is, the church; compare the notes on Hebrews 3:1-6. Under the Jewish dispensation there was a great high priest, and the same is true under the Christian dispensation. This the apostle had shown at length in the previous part of the Epistle. The idea here is, that as under the former dispensation it was regarded as a privilege that the people of God might have access to the mercy-seat by means of the high priest; so it is true in a much higher sense that we may now have access to God through our greater and more glorious High Priest.

A high priest over the house of God - The house or family of God is the Christian Church, or all true believers in the Lord Jesus. Over this Church, house, or family, Christ is the High Priest - in their behalf he offers his own blood, and their prayers and praises; and as the high priest had the ordering of all things that appertained to the house and worship of God, so has Christ in the government of his Church. This government he never gave into other hands. As none can govern and preserve the world but God, so none can govern and save the Church but the Lord Jesus: He is over the house; He is its President; he instructs, protects, guides, feeds, defends, and saves the flock. Those who have such a President may well have confidence; for with him is the fountain of life, and he has all power in the heavens and in the earth.

And having an high priest over the house of God. The church of God, over which Christ is as prophet, priest, and King, and as the Son and owner of it; See Gill on Hebrews 3:6; See Gill on Hebrews 4:14. In the Greek text it is, "a great priest"; so the Messiah is called by the Targum on Zechariah 6:12 , "a great priest", as he is; even a great high priest, as in Hebrews 4:14, and greater than Aaron, and any of his sons.

A high priest (ἱερέα μέγαν)

Lit. a great priest. Comp. Leviticus 21:10, lxx. Not merely equals ἀρχιερεὺς high priest, but emphasizing Christ's superior greatness as high priest.

House of God (οἶκον τοῦ θεοῦ)

In the Gospels always of the temple. Not found in Paul. Once in the Pastorals, of the church, 1 Timothy 3:15, and so 1 Peter 4:17. Here the whole Christian family. Comp. 1 Corinthians 3:16, 1 Corinthians 3:17; 2 Corinthians 6:16; Ephesians 2:22.

And having an high priest over the house of God;

10:21 And having an high priest. Our high priest hath opened the way by rending the veil. He is priest

over the House of God, the church on earth, and our high priest in the Holiest of all above.

21. high priest-As a different Greek term (archiereus) is used always elsewhere in this Epistle for "high priest," translate as Greek here, "A Great Priest"; one who is at once King and "Priest on His throne" (Zec 6:13); a royal Priest, and a priestly King.

house of God-the spiritual house, the Church, made up of believers, whose home is heaven, where Jesus now is (Heb 12:22, 23). Thus, by "the house of God," over which Jesus is, heaven is included in meaning, as well as the Church, whose home it is.

10:19-25 The apostle having closed the first part of the epistle, the doctrine is applied to practical purposes. As believers had an open way to the presence of God, it became them to use this privilege. The way and means by which Christians enjoy such privileges, is by the blood of Jesus, by the merit of that blood which he offered up as an atoning sacrifice. The agreement of infinite holiness with pardoning mercy, was not clearly understood till the human nature of Christ, the Son of God, was wounded and bruised for our sins. Our way to heaven is by a crucified Saviour; his death is to us the way of life, and to those who believe this, he will be precious. They must draw near to God; it would be contempt of Christ, still to keep at a distance. Their bodies were to be washed with pure water, alluding to the cleansings directed under the law: thus the use of water in baptism, was to remind Christians that their conduct should be pure and holy. While they derived comfort and grace from their reconciled Father to their own souls, they would adorn the doctrine of God their Saviour in all things. Believers are to consider how they can be of service to each other, especially stirring up each other to the more vigorous and abundant exercise of love, and the practice of good works. The communion of saints is a great help and privilege, and a means of stedfastness and perseverance. We should observe the coming of times of trial, and be thereby quickened to greater diligence. There is a trying day coming on all men, the day of our death.
